s an incosing membe" Sat-e of California, have iwenerl Be 1t. known that Gzonr, C( oltlzen of the Umted Q* emie ref Oakland, in the county of fzme new and useful mprovexoenis in S '/echanism, of which he o. speccat-ion.

The pl'esen; invention relates to 2L mfig construction for shifting devees? and. for its principal object *i0 neorpomte i construction, 'wherein the op fxion oluteh' pedal to release the cueh of the operation of the shfiing de mes, :L ock, whereby he shifting sevices Pour locked from operative movement @mea ai le same me permitting bhe opemioo o cluzh.

With the above mentioned am@ jees in View, the invenipioo ooros novel construction and Combination o heresfer dosczibede ust'eed io oompanyng drawings. md pofne the claims hereto appended; it ik Stood that various c-'mnges in he portion, size and mino?? i tion Wthi'n the scope of he demas resortec to Withom'; depmng o? sacong :my oif -le advantages f' nvenion. o

Figure l is e View in side eeY-.faony in seoon, of the prefe'ed omhoo" my invention.

Fig. 2 is a View in on line of Fig.

"4 y3i is a modified form o Wherem .the ooingg: ogers f1 Fig. 4. is o.V sootooa View of Figr 2. v,

Beerng more pareuoly ings, wherein ef i designa/5e corresponding pa-its s'oitabo gear casing associated 2y o? my f form or dutch, the constmcion heein tinted being in the form of wlaft is o monly termed a unz power pz:.n1,

Slidably mountefi -zdnef o ngs in the emi Wa's of cesa il; the `gears vvhen the same are in motion. he. texible connection 'between the pedal 2G and shaft 'i9 permits the disengagement of member during such time as the vices are locked from operative einen', either in neutral position or in e ed position by the locking means herei A described.

aiding through the cover 7 and interthe bore in which the shaft 19 is ta ily mounted, is a suitable bore 28 in eh is mounted for axial rotation the bolt '29, having a recess 30 adapted Kceive the periphery of the shaft 19 and "permit rotation of said shaft. The peripheral snr'tace of the bolt is also adapted tor reception in the corresponding' recess 3l in the. shaft i9 when it is desired to lock said sli-att irom movement. 3;5. fnerotation of the bolt to locked position, as in Fig'. 2 of the d 'aWings7 is accomnlished by a suitable handle 32 extending through an opening in the casing- 34 snrroum'lingsaid bolt, and the bolt is adapted to be held in locked position by a key eon- 1li-oiled lock 35, of any suitable type. 0n the releasing ot' said lock through the actuation oi' the hey, a spring 86 is adapted tor rotating' the bolt a one-quarter revolution to unlocked position, as in the modified construction illust-rated in Fig. 3.

he lingers 1S are extended to a point 'where the curved ends of the same project into the recesses ,10 in the shifter device-s at opposite sides ofthe lever 8 and thus lock the `lever trom lateral or selective moveand simnltanemisly locking' the shifter ices from operation.

improved construction it will be apparent that the shifter devices are capable oit operation only during such times as the clutch is in released position and then through the elevating of the ngersV 18. Y mvevei die lingers may be locked in .en-

nient with the lugs le either when the are in nent-ral or in engaged position, venting opei ition of the vehicle, but ulti it desired to mannallv move the the connece a garage or the lilze, n bei wenn the motor and the rear or driving' vvh may be broken or interrupted by the throwing out or releasing of the clutch.

aving thus described my invention, what E claim as new and desire to protect by Leters iatent is A gear shifting device including a casgear shifter elements therein provided vfith stops, a hand device for operating elements, swinging fingers coperatingrj with said elements for locking the same in their adjusted position, said fingers 'tun-ruined at one end and their free, ends 'ed for swinging' movement into and oi engagement vvith said stops, and

ont

Lacasse leasable lock controlled means for locking said lingers in engagement with said stops.

in combination with a variable speed power transmitting' mechanism includingshifter devices, of a clutch and .'iperalinfg means therefor for controlling the driving' connection to said mechanism, means 'tor operating said shifter devices, shifter device retaining means, a yieldable connection between said clutch operating' means and said shifter device retaining' means wherebvv said retaining means is released to permit the operation of said shifter devices on the release of said clutch, and means for locking' said shifter device retaining' means in engagement with said shifter devices, wherehvv the operation of said shifter devices is precluded on the release ot said clutch.

ln combination with a variable speed povver transmitting mechanism including shifter devices, of a clutch and operating means therefor 'for controlling the driving conncctionl'o said mechanism, means 'for retaining said shifter devices from operative movement during' the engagement of the clutch, a connection between said clutch op @rating means and said shifter device retaining means, and means Ytor lockingv said shifter devices from movement without interiering with the operation oit the clutch.

4e. in combination with a variable speed power transn'iitting mechanism including` shifter devices, of a clutch and operatingy means therefor 'tor controlling` the driving' connection to said n'iechanism, means For 1 retainingV said shifter devices `from operative movement during' the engagement oi" the clutch, a connection between said clutch operating' means and said shifter device rctaining means, and means for loc/hing' said retaining means in engagement with, said shifter devices whereby said devices are locked from movement Without interiorineI with the operation oi the clutch.

A gear shifting device including' a, easing, gear shifter elements therein provided with stops, a hand device for operating said elements, swinging' lingers cooerating With said elements for locking the same in their adjusted position, said inn'ers tulcrnmed at one end and their 'tree ends adapted for swinging movement into and out ot' engagement with said stops. nminuallyv operated means independent oi said hand operated device for swinging said fingers on their fulcrunnand releasable lock controlled means for locking said fingers in engagement with said steps.

6. i gear shifting device including a casi g', a gear shifting' element therein provided With a stop, a device tor operating .said elcment, movable means cooperating with said elements for retaining the same in 'its adllo in engagement with said stop to preclude movement thereof, and foot actuated means for operating said movable means on the release of said locking n'iechanisi'm.r

7. In combination with avariable speed power transmitting mechanism-\including a casing and gear shift elements therein providcdwith stops, a clutch, ating sadclutch to control the driving connection to 'said power transmitting mechansm, movable means cgiperatii/igA with said elements for retaining the same in their adjusted position, releasable lock controlled mechanism for locking said movable means in engagement with said stops to preclude movement thereof, a connection between said clutch operating means and said movible means whereby the releasing of said neans.to release the same from said stops, ind a device for selectively operating said neans therefrom.'/ y

8. In combination with a variable speed means'r for oper- :hitch simultaneously operates said movable lements on the vrelease of said movable @EST'VAnAs're a power transmitting mechanism including gear shifting elements provided with stops, a clutch for controlling the driving connection to said power transmitting mechanism,

a foot operated lever capable of movement for releasing said clutch, means coperatmg with said elements for engagement there with to retain the same in their adjusted poi GEORGE o. JENSEN.
